Disruptive, crazy woman on flight who verbally assaulted flight attendants. Refused to leave plane when asked. Captain made smart decision to have all 180 passengers get off the plane to ensure our welfare until they got her off. Strategic, bold decision, although unfortunately it made others miss their connecting flights in Detroit. American Airlines staff performed admirably, especially the gentleman who spent most time talking to the crazy lady. He was professional, patient, empathetic, but also firm. She was threatening and uncompromising, threatening to have an epileptic seizure if he didn't leave her alone. He was awesome, as was the captain and flight attendants!
